Number pods ride a neon conveyor through machines like ×2 and +3, morphing as they go. Tune the gates to fill each order, reverse-engineer inputs, and crack mystery rules.
Numbers enter a conveyor of gates — multiply by two, add three, and so on — and the challenge shifts between tuning those gates to hit a required output and working backwards to find the original input. This builds fluency with function machines, pattern recognition, and inverse operations such as undoing multiplication with division. A good fit for Grades 4–6, or any child ready to think about operations as rules that can be reversed.
